Sleep deprivation could cause junk food cravings

CINCINNATI, OH (FOX19) -

If you crave chocolate or potato chips after a hectic day, it may be because you're sleep-deprived.

A new study found that lack of sleep may lead to increased appetite and an affinity for unhealthy foods.

Researchers at the University of Chicago say people who were tired, opted for snacks with more carbs and nearly twice as much fat and protein compared to those who were well-rested.

The team's previous research suggested that sleep deprivation affected levels of endocannabinoids, chemicals in the brain that are involved in regulating appetite and bind to the same receptors as marijuana.

According to the Centers for Disease Control, one in three U.S. adults don't get enough sleep and roughly the same percentage are obese. 

Adults should get 7-8 hours of sleep while adolescents need 9-11 hours of sleep.
